Unknown Error at preflight

[artbycaf]

Hi there,

When I attempted to preflight a particualr PDF I'm getting an "Uknown error (unknow exception)". This happens with any type of preflight, even to check the syntax issues. I've tried it on two separate computers, both with Acrobat Pro DC (version 2017.009.20044), and both came up with the same error.

When I attempted the same preflight on a 2015 version of Acrobat Pro DC it worked.

As anyone else come across this problem.

I've been able to preflight other PDFs, it's just the one that is causing issues.

Thanks!

Hi Priyanka,

I've extracted one page from the problem file. I've tried again and I'm unable to preflight even this single page.

You may download it from:

Thank you for looking into this issue.

Kind regards,
